9:00 AM - MATERIALS SCIENCE AND ENGINEERING LABORATORY SEMINAR: Workshop on Nano Metrology of Materials
Scanning Probe Microscopy is used worldwide to characterize the properties and structures of materials. The techniques are especially good for examining local properties of materials for a wide range of material properties, including surface topology, surface and near surface friction, ferroelectric domain structure near surfaces, electric potential and impedance at surfaces and the atomic structure of crystals at surfaces. The piezoelectric transducers used as part of the atomic force microscope offer the possibility of manipulating materials for testing on the nano scale. In this regard, small mechanical test machines have been made that are able to measure the strength of specimens of micron dimension. A two day workshop on scanning probe microscopy will be held to familiarize interested staff in the diverse ways in which the technique is being used within NIST. The accent of the workshop will be the measurement of properties at the nanometer scale.

2:00 PM - BIOTECHNOLOGY DIVISION SEMINAR: Nucleation, Growth and Scaling of Pentacene Films on modified Si Substrates
Organic/inorganic interfaces play a crucial role in the currently growing field of molecular electronics. Even though huge progress has been achieved in the understanding of electronic transport in conjugated molecular materials, a complete theory to model and tailor nucleation, growth and film morphology of organic materials deposited on inorganic substrates is still missing. A systematic study involving complementary techniques such as atomic force microscopy (AFM) and synchrotron X-ray scattering, is reported. We employ dynamic scaling theory that has been used in the past for inorganic materials to analyze the island size distribution, critical cluster size and island correlations. We demonstrate the scaling behavior of the island size distribution of pentacene in the aggregation regime (0.1 to 0.5 monolayers) indicating that surface diffusion laws govern the system. The particular distribution of the scaling function suggests that the minimum number of molecules that conform a stable nucleus is 4. The island-island correlation length in the aggregation regime and the scaling of the structure factor of the film density were also measured using AFM and diffuse X-ray scattering with consistent results between the two methods and in agreement with dynamic scaling theories for diffusion limited systems. The structure factor could also be explained as the product of two functions: the single island form factor and the spatial distribution of the islands. The present work demonstrates that it is possible to apply existing models to organic/inorganic interfaces even though concepts like lattice mismatch and the strong covalent bondings are absent.

1/29 -- WEDNESDAY

10:30 AM - ITL SEMINAR SERIES: Fuzzy Logic, or How I Learned to Stopy Worrying and Love Partial Set Membership
Fuzzy logic allows inference and computations based on partial membership of entities in given sets. In practice, it allows machines to deal cleanly and robustly with natural imprecision, and has spawned applications in a variety of areas. It has facilitated programming of neural networks, decision aids, expert systems, and controllers. In modeling, it can improve on traditional approaches, as it lends itself to traditional coding methods with less code complexity As an example, the speaker will use an ultimately neuro-fuzzy implementation of a high-order differential-equation-based muscle force estimation model that she is developing. Some background on fuzzy logic and its applications will be given to demonstrate the benefits of using it, and potential future uses of fuzzy logic will be discussed. Bio: Amy J. O'Brien (aobrien@dsrnet.com) is a systems engineer with Digital System Resources, Inc. in Fairfax, VA and is finishing her PhD in Electrical Engineering at George Washington University. Her dissertation involves control-theoretic systems modeling, soft computing, and biomedical engineering. Her current research involves developing an ultimately neuro-fuzzy implementation of a high-order differential-equation-based muscle force estimation model. She has publications related to her research and to a powerful generalized fuzzy inference engine she developed to support it. She regularly presents fuzzy logic tutorials.

11:00 AM - PHYSICS LABORATORY SEMINAR: Going Deep - Discovering Opportunities at a National Underground Science and Engineering Laboratory
Physics is in the midst of two major intellectual revolutions: uncovering the nature of physics beyond the Standard Model and revealing the secrets of the cosmos through a variety of nuclear physics,  particle physics, and precision astrophysical measurements. Recent exciting discoveries in neutrino astrophysics from underground detectors have provided the first clear evidence for "new" physics beyond the Standard Model. A deep underground science laboratory will play a leading role in both of these revolutions, housing next generation experiments that will answer significant questions, in nuclear physics, particle physics, astrophysics, and cosmology. In addition to the pure physical sciences, a vast range of both fundamental and practical subjects, such as biology, geology, and national security will also benefit from the establishment of such a laboratory. This talk will review the potential science to be done underground and report on the  progress that has been made in the past two years in the efforts to establish a National Underground Science and Engineering Laboratory (NUSEL) within the United States.

2:00 PM - ELECTRON AND OPTICAL PHYSICS DIVISION SEMINAR: Diederik Korteweg, Pioneer of Criticality
The late 19th century studies of Dutch mathematician Diederik Johannes Korteweg (1848-1941) anticipated important work to be done in the 20th century, and the types of questions he tackled continue to be of interest. He is best known for the 1895 paper he wrote with his student Gustav De Vries. That paper, on the propagation of soliton waves in channels, has, in recent decades, been widely recognized as a groundbreaking work. Korteweg also studied the stress--now called the Korteweg stress--resulting from density gradients at an interface between two fluids. His contributions to the thermodynamics of phase transitions and criticality in fluid mixtures, which will be discussed in this talk, are less well known. They include honing the tools of differential geometry to characterize phase separation and criticality of fluid mixtures, developing a method of deformation of surfaces, and performing the first detailed analysis of the phase behavior of a special case of the van der Waals equation for binary fluid mixtures. Dr. Sengers is a Scientist Emeritus at NIST, and a member of the National Academy of Engineering and the National Academy of Sciences. She is the author of "How Fluids Unmix: Discoveries by the School of Van der Waals and Kamerlingh Onnes," (Edita, Royal Netherlands Academy of Arts and Sciences, Amsterdam, 2002), and of an article on Korteweg in the December 2002 issue of Physics Today.
